非线性系统事件触发控制的统一Lyapunov框架

A unifying Lyapunov-based framework for the event-triggered control of nonlinear systems

Romain Postoyan, Adolfo Anta, Dragan Nesic, Paulo Tabuada

摘要:

我们提出了一个规范性的框架事件触发控制的非线性系统。在事件触发的实现中,不是像传统的数字控制那样周期性地闭合环路,而是根据状态相关的标准来闭合环路。事件触发控制特别适用于嵌入式系统和网络化控制系统,因为它减少了控制所需的资源量,如通信带宽。通过将事件触发实现建模为混合系统,我们提供了基于Lyapunov的条件来保证所得到的闭环系统的稳定性,并解释了如何利用它们来合成事件触发规则。我们说明了一般性的方法,它包括几个现有的事件触发政策,并通过开发新的战略,进一步减少控制所需的资源。

英文摘要:

We present a prescriptive framework for the event-triggered control of nonlinear systems. Rather than closing the loop periodically, as traditionally done in digital control, in event-triggered implementations the loop is closed according to a state-dependent criterion. Event-triggered control is especially well suited for embedded systems and networked control systems since it reduces the amount of resources needed for control such as communication bandwidth. By modeling the event-triggered implementations as hybrid systems, we provide Lyapunov-based conditions to guarantee the stability of the resulting closed-loop system and explain how they can be utilized to synthesize event-triggering rules. We illustrate the generality of the approach by showing how it encompasses several existing event-triggering policies and by developing new strategies which further reduce the resources needed for control.
